Was Einstein wrong about the speed of light?

Albert Einstein's Theory of Relativity states that no object in the universe can travel faster than the speed of light in a vacuum. Scientists at CERN have that have exceeded that speed limit, even if by billionths of a second. They are now seeking scrutiny of their testing as confirmation could shake physics up a bit.

The teamso other scientists can determine if the approach contains any mistakes.

If it does not, one of the pillars of modern science will come tumbling down.

Antonio Ereditato added "words of caution" to his Cern presentation because of the "potentially great impact on physics" of the result.

The speed of light is widely held to be the Universe's ultimate speed limit, and much of modern physics - as laid out in part by Albert Einstein in his theory of special relativity - depends on the idea that nothing can exceed it.

Thousands of experiments have been undertaken to measure it ever more precisely, and no result has ever spotted a particle breaking the limit.

"We tried to find all possible explanations for this," the report's author Antonio Ereditato oftold BBC News on Thursday evening.

"We wanted to find a mistake - trivial mistakes, more complicated mistakes, or nasty effects - and we didn't.

Gamers solve in weeks what scientists couldn't in a decade

Way cool. Using , gamers were challenged to find the structure of a protein related to the AIDS virus. They did it in a matter of weeks when the scientific community had been working on it for over 10 years.

When scientists struggle with a problem for over a decade, few of them think, “I know! I’ll ask computer gamers to help.” That, however, is exactly what  from the University of Washington did. The result: he and his legion of gaming co-authors have cracked a longstanding problem in AIDS research that scientists have puzzled over for years. It took them three weeks.

Khatib’s recruits played Foldit, a programme that reframes fiendish scientific challenges as a competitive multiplayer computer game. It taps into the collective problem-solving skills of tens of thousands of people, most of whom have little or no background in science. .

Google Chrome no longer works right with Facebook, until...

I first noticed the problem when trying to "Like" someone else's status. It would take me to a blank page and nothing else would happen. While looking into the problem, I found others with related issues that I had not noticed yet. I thought a recent update of Chrome may have broken AJAX.

I tried clearing my cache and cookies and rebooting as some had suggested, but to no avail. What did end up solving the problem was using SSL to get to Facebook. Once I went to https://www.facebook.com/ everything started working correctly again. I also noticed a prompt at the top of the page asking me to turn on Facebook security, which forces SSL.

I came to the conclusion that Facebook made a change to their code that supports the new security features but breaks Chrome by default. Only when you first access it with https and then accept the new security will it work properly again.

Bookmarklet for posting page selection to a Drupal CMS

I thought I would share this because I have not seen this functionality posted elsewhere.

I have been searching for a way to post content from one website to my own Drupal site without going through the process of copy/paste/format. There are several examples out there, but none did exactly what I was wanting. With the help of one Mr. Andy K., I have something that works pretty well. Thanks Andy!

This is what I found in the for the Drupal module "" (required for this to work). The basic instructions are to copy this and past it into the location of a new bookmark in your browser. It has to be a single line of script to work. The problem is that it copies the text of the page and not the formatted html, causing more work to be done after it populates the node/add form:

javascript:u=document.location.href;t=document.title;s=window.getSelection();void(window.open(%22http://example.com/node/add/blog?edit[title]=%22+escape(t)+'&edit[body_field][body]='+escape(s)+'&edit[field_link][0][url]='+escape(u)+'&edit[field_link][0][title]='+escape(t),'_blank','width=1024,height=500,status=yes,resizable=yes,scrollbars=yes'));

NSSF Shooting Sportscast: Understanding Mils for ranging targets

Really good information on using mil-dot rifle scopes. I think it might all sink in after watching a few more times Wink

Innocent until proven guilty or innocent until looking guilty?

. "Minority Report" technology that can sense whether you are about to commit a crime.

Future Attribute Screening Technology (FAST), a US Department of Homeland Security (DHS) programme designed to spot people who are intending to commit a terrorist act, has in the past few months completed its first round of field tests at an undisclosed location in the northeast, Nature has learned.

Like a lie detector, FAST measures a variety of physiological indicators, ranging from heart rate to the steadiness of a person's gaze, to judge a subject's state of mind. But there are major differences from the polygraph. FAST relies on non-contact sensors, so it can measure indicators as someone walks through a corridor at an airport, and it does not depend on active questioning of the subject.

Nothing else I can think of could possibly cause increased heart rate and nervous behavior so there's no way this could result in false positives. Right?

Some scientists question whether there really are unique signatures for 'malintent' — the agency's term for the intention to cause harm — that can be differentiated from the normal anxieties of travel. "Even having an iris scan or fingerprint read at immigration is enough to raise the heart rate of most legitimate travellers," says Ormerod.

Depixelizing Pixel Art: Upscaling Retro 8-bit Games

This is pretty stinkin' cool. Although this demonstration is for video games, the first thing I thought of when I saw this was that I won't be able to make fun of CSI zoom-and-enhance techniques any more.

Two researchers -- Johannes Kopf from Microsoft, and Dani Lischinski from The Hebrew University -- have successfully created an algorithm that depixelizes and upscales low-resolution 8-bit "pixel art" into lush vector graphics. The algorithm identifies pixel-level details to accurately shade the new image -- but more importantly, the algorithm can create smooth, curved contour lines from only-connected-on-the-diagonal single pixels. Look at the Super Mario World dolphin below, and compare it to the original source sprite below that: the results speak for themselves.
